Festival goers planning to don the denim shorts and colorful vests for the weekend would be better served in wellies and raincoats - because it’s going to be wet.

The three days of Longitude festival in Marlay Park in Dublin are set to be dominated by cold, wet, windy weather.

There’s a National Weather Warning in place today for the west with winds of 40 to 50km/h set to batter the coastal counties. So anyone walking around on stilts or juggling at the Galway International Arts Festival better make sure to keep their act low to the ground.

Winds won’t be quite so fierce on the east coast, but Willemien Phelan of Met Éireann has said that “everything will be shaking around a good bit this afternoon and evening” at Longitude.

Rain is on the bill again for tomorrow across the midlands and over to the east, but the north and the south should miss the worst of it.

It will be blustery in the morning but winds are set die down into the afternoon making it a little bit warmer at least.

Temperatures will hover around the mid-teens for the weekend but persistent wind will make it feel colder.

The worst weather will come Saturday night with heavy rain all across the country and showers continuing into Sunday morning.

But there could be light at the end of the tunnel: the rain is set to taper off on Sunday afternoon and the sun might even poke its head out.
